Introduction
Welcome to Moxa NPort Express, a compact palm-sized communications device
that allows you to control RS-232/422/485 serial devices over a TCP/IP Ethernet.

NPort Express DE-211 provides a data communications solution for connecting
Windows and Linux hosts to asynchronous serial devices over a TCP/IP Ethernet.
You may connect your Windows 95/98/ME/NT/2000/XP host to a native
RS-232/422/485 serial port, or your PC-based Linux host to a real tty port, through a
TCP/IP Ethernet. With one asynchronous serial port connection on one end, and a
10 Mbps Ethernet connection on the other, NPort Express allows
virtually any serial device to attach to a network. NPort Express works like an
add-on single-port serial board to your PC server, but with one major advantage—the
TCP/IP network. Since the host communicates with the COM port on NPort
Express over a TCP/IP network, you are able to control your asynchronous serial
device from virtually any location.
Although it connects through the virtual link of the Ethernet, the port on NPort
Express is recognized as a real COM port by Windows or a real tty port by Linux.
NPort Express provides both the basic transmit/receive data functions, as well as
RTS, CTS, DTR, DSR, and DCD control signals.
NPort Express can be used with your existing applications that support serial
communication, and come with a utility program providing a simple step-by-step
installation procedure and a maintenance wizard that gives you easy access to your
asynchronous device.

DIN Rail
For many industrial applications, you will find it convenient to use the DIN Rail
attachments, as shown below.
STEP 1: Use 2 screws per ear to attach DIN Rail mounts to each of NPort
Express’s two ears.
⇒
STEP 2: Insert the top of the DIN Rail STEP 3: Push the bottom of NPort
into slot A of the DIN Rail
mount.
Express so that the bottom of
the DIN Rail snaps into slot B
of the DIN Rail mount.
ꢀ
NOTE: The Din Rail mounting kit is an optional accessory.
To remove NPort Express from the DIN Rail, simply reverse Steps 2 and 3 above by
grasping the bottom of the NPort Express unit with both hands, and then using your
fingers to pull down slightly on the DIN Rail mounts at slot B. This releases the
bottom of the DIN Rail from the DIN Rail mount.
2-2
Wall Mount
For many industrial applications, you will find it convenient to mount NPort
Express on the wall, using two screws, as indicated below.
STEP 1: Screw two screws, separated by 7.8 cm, into the wall. The heads of the
screws should be no greater than 6.5 mm in diameter, and the shafts
should be no greater than 3 mm in diameter. Do not screw the screws in
all the way—leave a space of about 2 mm to allow room for sliding the
NPort Express unit’s ears between the wall and the screws.
STEP 2: Insert the two screw heads
through the large parts of the
keyhole shaped apertures, and
then slide NPort Express
STEP 3: For added stability, simply
tighten the two screws.
downwards, as indicated.
To remove NPort Express from the wall mount, simply reverse Steps 2 and 3.

Switch SW1 controls the function of the serial port (ON, or up, for RS-232
Console connection, and down for Data Communication, such as when NPort
Express is connected to your serial device). Note that after changing the setting of
SW1, NPort Express will reboot to initialize the new setting. You must wait a few
seconds for the green Ready light to blink off and then on again, indicating that the
function of the serial port has been changed.
Switches SW2, SW3, and SW4 control the serial port’s data communication
Interface Mode. (Note that RTS stands for Ready To Send and ADDC stands for
Automatic Data Direction Control.)
Keep the following points in mind when setting the DIP switches.

RS-232 Console
To use the serial port as a console connection, such as when using MOXA
PComm Terminal Emulator or HyperTerminal, set SW1 to the ON position.
Telnet Connection
Some setup procedures can be carried out through a Telnet connection,
during which data is transmitted through NPort Express’s Ethernet port.
However, you must set SW1 to the OFF position to establish a Telnet
connection.

NOTE: When setting up a multidrop network, a daisy-chained network should
be used. Construct your device-to-device wiring as indicated in the
above figure.
Enabling a Termination Resistor
For RS-422/485 serial communications, when an electrical signal travels through
two different resistance junctions in a transmission line, the impedance mismatch
will sometimes cause signal reflection. Signal reflection causes signal distortion,
which in turn will contribute to communication errors. The solution to this problem
is to establish the same impedance at the line ends as in the line itself, by
terminating them with resistors.
The impedance of the termination resistor should equal the characteristic impedance
of the transmission line. The resistors should be added near the receiving side.
3-8
Enabling the Built-In 120 Ω Terminator
To enable NPort Express’s built-in 120 Ω termination resistor, you must short the
bottom two pins of jumper 6 (JP6), on DE-211’s circuit board. To do this:
1. Use a screwdriver to remove DE-211’s outer protective case, and then locate
JP6, as shown in the figures below.
2. By default, the top two pins of JP6 are shorted, which means that the built-in
120 Ω termination resistor is disabled (completely removing the jumper from
the pins also disables the resistor).
3. Use the jumper to short the bottom two pins of JP6 to enable the built-in 120 Ω
termination resistor.
3-9
Enabling a User-Supplied Terminator
When using the terminal block, you may install your own external terminator
resistor by connecting the ends of the resistor directly to inputs 2 and 3, or by
connecting the two ends of the resistor to the wires that emanate from inputs 2 and 3,
as shown in the following diagrams.

Ethernet Installation
We discuss the following topics:
¾
Connecting to the Ethernet Port
• Connecting to a Hub or Switch
• Connecting to a PC
Connecting to the Ethernet Port
Connecting to a Hub or Switch
For most applications, you will simply plug one end of your Ethernet cable into
NPort Express’s 10BaseT port, and the other end into a Hub or Switch that is
connected to your network. In this case, you should use a standard straight-through
Ethernet cable, which is readily available from many commercial vendors. If
necessary however, you can make your own cable by referring to the following
cable wiring diagram.
Connecting to a PC
In some cases, such as when configuring drivers and software, you will find it
convenient to hook NPort Express directly to your computer’s Ethernet card. To do
this, you will need to use a cross-over Ethernet cable. This type of Ethernet cable is
harder to find, although you can make your own cable by referring to the following
cable wiring diagram.

Power Connection
We discuss the following topics:

Using the Power Adapter
Using Power Over Serial
Power Status Check
Using the Power Adapter
Take the following steps to connect NPort Express’s power adapter.
1. Plug the power adapter’s DC plug into NPort Express’s DC-IN jack.
2. Plug the power adapter into an electrical outlet.
Note that there is no on/off switch. The server turns on as soon as the connected
power adapter is plugged into a live outlet. The red PWR light on NPort Express’s
top panel will glow to indicate that it is receiving power.
Using Power Over Serial
Take the following steps to set up NPort Express’s Power over Serial option.
IMPORTANT NOTICE
You may not use the power adapter and Power Over Serial option at the same time.
Using both power options at the same time could cause irreparable damage to your
NPort Express unit.
(1) To use the 12 – 30 VDC Power over Serial option, enable jumpers JP4 and JP5,
as illustrated in the following diagram. Note that when using the 12 – 30 VDC
option, power is supplied via pins 12 and 13:
5-2
Do NOT force either jumper horizontally, as shown in the
diagram. Doing so could cause serious damage to your DE-211, or
to the serial device connected to DE-211’s serial port.
To use the 5 VDC Power over Serial option, enable jumpers JP2 and
JP3, as illustrated in the following diagram. Note that when using the
5 VDC option, power is
supplied via pins 9 and
10:
Do NOT force the jumper to connect the lower pin of JP2 to the
upper pin of JP3, as shown in the diagram. Doing so could cause
serious damage to your DE-211, or to the serial device connected
to DE-211’s serial port.
Power Status Check
Use the PWR LED indicator on NPort Express’s top panel to see if it is receiving
power. A red light indicates that power is being received. The absence of a light
indicates that power is not being received. If the unit is plugged in, or is receiving
power over cable, then an unlit PWR LED indicator shows that something is wrong
with the NPort Express unit’s operation.
